PAGE 14 — STOW CUTTER 1 SAW — OPERATION & PARTS MANUAL — REV. #6 (06/06/08)
STOW CUTTER 1 SAW — PREPARATION/PRE-INSPECTION
PREPARATION / PRE-INSPECTION
1. Read and fully understand this manual,
the safety instructions in particular, and
the engine manufacturer's manual
supplied with the saw.
ALWAYS use a grounded (3-wire) extension cord and MAKE
CERTAIN that the motor is connected to a properly grounded
electric circuit to protect the operator from possible electric shock.
2. Select the correct blade for each application. If abrasive
blades are used, MAKE CERTAIN they are designed for
use on a concrete floor saw. They must be reinforced and
have a hole for the driving pin. When wet cutting with an
abrasive blade, MAKE CERTAIN the blade is intended for
wet cutting. Water will destroy a dry cut abrasive blade.
Some diamond blades require water cooling and failure to
do so will destroy them almost immediately. Other diamond
blades can be used with or without water. Refer to the Blades
and Blade Placement sections on pages 18 and 19 for further
information.
3. Handle all blades with care and NEVER use a damaged
blade. NEVER use an abrasive blade that has been
dropped.
Electric Powered Saws (50 or 60 HZ)
1. The electric motor of this saw requires 230 VAC input
voltage (50/60 Hz, single-phase). Always make certain that
the rated operating line voltage of the motor is correct when
cutting. Electric motors can burn out when the line voltage
Gasoline Powered Saws
falls 10% below the voltage rating of the motor.
2. After the correct input voltage has been applied to the saw,
turn the saw on, and check the rotation of the motor shaft.
The shaft rotation MUST be counter-clockwise when
viewing the motor from the shaft extension end. If the rotation
of the shaft is incorrect make the necessary changes for
the correct shaft rotation.
3. MAKE CERTAIN the correct size extension cord is used.
Undersize extension cords can burn out an electric motor.
Use Table 3 to determine the correct extension cord size.

V-belt Alignment and Tensioning
This saw is equipped with a premium V-belt that has been aligned
and tensioned by factory personnel. The V-belt must be aligned
and tensioned for proper operation of the saw.
Use the following procedure to check the alignment of V-belt:
1. Remove the bolts that secure the V-belt cover (Figure 9) to
the saw frame.
Figure 9. V-Belt Cover
2. Check uniform parallelism (Figure 10) of V-belt and pulley
(sheaves). Use a straight-edge or machinist's square against
both pulleys and adjust both pulleys until equally aligned.
Figure 10. Pulley Alignment
3. Check V-belt tension by using a tension meter (3.0 lbs.)
against the inside belt at a mid point between the two pulleys,
or by deflecting the center belt at a mid point 3/16" (5 mm).
4. DO NOT over or under tighten the V-belt. Severe damage
can occur to the saw and engine crankshaft if the belt is
over-tensioned. A decrease of power to the blade and poor
performance will result if the belt is under-tensioned (loose
on pulleys).
V-belt alignment must be

STOW CUTTER 1 SAW — BLADES
BLADES
Saw blades, or cutting disks, are available in either an abrasive
design or as diamond blades. Either blade will work on the
STOW CUTTER 1 SAW , however, diamond blades are
recommended. Ask your dealer about your specific cutting
application.
SAW BLADE INSPECTION
WARNING
Failure to thoroughly inspect the diamond
blade (Figure 11) for operational safety
could result in damage to the blades or
the saw and may cause injury to the user
or others in the operating area.
2. Edge of the Steel Core - Check the diameter edge for
discoloration (blue oxidation) indicating an overheating
condition caused by insufficient cooling water/air.
Overheating of blades may lead to loss of core tension and/
or increase the possibility for blade failure. Make sure the
steel core's width is uniform about the rim of the blade, and
not succumbing to an "under-cutting" condition brought
about by highly abrasive material or improper under-cutting
core protection.
3. Directional Arrow - Ensure that the blade is oriented
properly on the blade shaft for sawing. Reference the
directional arrow on the blade and place it so the direction
of rotation "downcuts" with the turn of the shaft.
4. Diamond Segment or Rim - Ensure there are no cracks,
dings, or missing portions of the diamond segment/rim. DO
NOT

5. Specifications - Ensure that the blade specifications, size,
and diameter properly match up to sawing operations.
Utilizing a blade not matched properly to the task may result
in poor performance and/or blade damage.
use a blade that is missing a segment or a portion
Damaged and /or missing segments/rims may
Figure 11. Diamond Blade
6. Arbor Hole - It is essential that the arbor hole diameter
properly matches the blade, and that it is free from distortion.
Correct blade flanges (collars) must be used. The inside
face of the flanges must be clean and free of debris. An outof-round arbor condition will cause damage to the blade
and the saw.
7. MAX RPM - This RPM reference is the maximum safe
operating speed for the blade selected. NEVER exceed the
max RPM on the diamond blade. Exceeding the maximum
RPM is dangerous and may cause poor performance and
may damage the blade.

WARNING
Failure to thoroughly inspect the diamond
blade for operational safety could result in
damage to the blades or the saw and may
cause injury to the user or others in the
operating area.
1. Blade Guard - Pivot the blade guard
front cover all the way back. The guard
tension spring will keep the front cover in position.
2. Blade Hex Nut - Unscrew the blade shaft nut (right side
loosens clockwise and tightens counter-clockwise while the
left side loosens counter-clockwise and tightens clockwise.
DO NOT overtighten the nut (approximately 45-50 ft. lb/6168 N/m) when finalizing the assembly.
3. Outside Blade Flange (Collar) - Ensure that the outside
blade flange is placed flush against the diamond blade.
The inside surface of the flange must be free of debris and
permit a tight closure on the surface of the blade core.
4. Diamond Blade - Ensure that the proper diamond blade
has been selected for the job. Pay close attention to the
directional arrows on the blade. The blade's operating
directional arrows must point in a "down-cutting" direction
to perform correctly. When placing the blade onto the blade
shaft, ensure the arbor hole of the blade matches the
diameter of the shaft.

Chassis Lubrication
■
Blade Shaft Bearings - Two zerk fittings are located at
the lower-front area of the saw. Lubricate before daily
use. Use a good quality automotive or general purpose
grease. Check and lubricate more often if unit is under
heavy use. Do not overfill bearings. Overfilling can
damage the grease seals which can result in bearing
exposure to dirt and contaminants which can then shorten
the life of the bearings. Excess grease can also drip onto
the cutting surface.
